Application filed May 15, 1912. Serial No. 697,406.

To all 'u1/omit may concern:

Be it known thatl, JOHN-J. HOFFMAN, a citizen of the United States, and a resident of theicity of New Kensington, in the county nia, hafe invented a. new and useful lmprovement in Car-Roofs, of whichA the following isa specification.

My invention relates to outside metal roofs for freight cars of the type shown in Patent No. 999,166 granted July 25, 1911, and resides in van improved form of flashing strip for the eaves' joints of the metal roof sheets of which the roof covering is composed, and in improved means for securing the roof covering upon the roof substructure or framing of the car.

The object of my invention is to eliminate thepossibility lof watergetting in the joint between t-he eaves ends of the roof sheets and the flashing, and toreduee `the chalingbetween the flashingstrip and thereof sheet, thus largely preventing the gisting out of the roof sheets at thev eaves of tflecar;

Another. object of my invention is to 'dispense zwith clips or other fastening means for securing the roofV covering along the eaves of the car between the roof sheet joints, and to form and arrange-the flashing strips in such manner that the flashing itself shall sufticien't-ly secure the Aeaves ends 0f the sheets.

Further objects of my inventionvwill ap-V pear in connection with the description of the embodiment thereof illustrated in the ac# lcompanyingdrawings, and the novel feal turesof. my invention will be more particularly pointed out inthe appended elaimsf In the drawings, in which like characters Wherever they@ appear throughout the several views are used to Vdesignate like parts, Figurel'is av vertical transverse section through the eaves of a car embodying my invention, showing a roof clip in elevation;

'.Fig. 2 is a view in side elevation of a portion of a car at-the eaves, showing the lower 'Ledges of twoA roof sheets and 'a roof clip and flashing stripgfFig. 3 isa perspective View` of a portion of'aflashing strip; Figi. 4 is a Aperspective View of a right hand eaves corner of a roof sheet; and FigQ 1s a perspective view of left hand eaves corner of a similar roof sheet. of "estmoreland and State of Pennsylvaf.

Inl thedrawings I. have illustrated my invention embodied in a metal roof for a box car havingr a wood side plate 1, side sheath ing 2, and roof sheathing 3, and fascia board '1, but its use is not restricted to cars having wood bodies. Preferably, lthe boards of the roof sheathing extend longitudinally and the outermost board overlaps the side plate. The edge portion of the wooden sheathingr or substructure for a 'distance of approximately four inches from the edge of the roof is offset or rabbeted (as shown at 5) so that its "surface is lower than the plane of the surface vof'the main-portion of'snch sheathing, in order to accommodate the rehent ends or interloeled flanges hereinafter mentioned. The metal roof sheets 6 lie tlatwise on the sheathing and' are arranged transversely of the-car. VThey are connected at their side edgesjby rebent flanges f7, l?,or interloclringv 'seams ofany suitable type. which will permit ,limited relative movement ofthe sheets." Theouter end 8 of each sheet is rebe'nt to lie the rabbe't of the sheathing parallel with the body of the sheet'and at. a slight distance below suchbody, the rebend being made along a line close to thc eaves or edge of the car. f

vSecured in the depressed marginal portion of the wooden sheathing is a flashing strip 9 whose outer marginal portion l() is bent down over the eaves, and nailed or otherA wise secured in the "rabbet along the upper edge of the fascia 4. The inner margin of this flashing strip is bent upwardly and -then baclrwardlyvso as to form flanges 1l which lie parallel with the body of the strip. The middle portion of the flashing strip is formed up into ribs or projecting portions 12, arranged parallel to each other at shory intervL s along the flashing, and having their upper faces spaced slightly below the rebent flanges 11. The reb'ent marginal'portions or`tlanges V11 of said flashing strips en gage therebent marginal portions 8 of the interlocking roof sheets, und the portions 12 of the strip support 'the roof sheets, out of Contact with the dashing' strip5 and allow imiter entering beneath fiiingosll to i'nii eti" the eaves instead of being caught by the rebenteiids' ie'rpofsheets. in practice,

tlie/i'ebends of. t e 'flfisliing strip-end of the roof sheets are so proportii'ned that norA portion. of the s videiboii the inneigfziw i lugg'sl adapt-arido beni- .mens' for positioning; the innT interi-'ene between tlioredge of therebent portion and the ioop with which it engages.
